About the Rfid PCB

Rfid is an open source ESP32 PCB design by LeafCodes, published on GitHub. It is a 2-layer board measuring 26.1 × 37.9 mm, with 8 components from 6 distinct parts.

Its main chip is the ESP32-S3-DevKitC, from the ESP32 family. By type, the board carries 2 connectors, 2 diodes, 2 resistors, 1 IC and 1 buzzer.

It belongs with the iot & wireless designs in this gallery.

From the project

Local-First & Offline-Resilient RFID Attendance System built with ESP32-S3, PlatformIO, Custom KiCad PCB, and FastAPI Backend.

Banyak institusi, sekolah, laboratorium, maupun startup menghadapi berbagai kendala dalam pencatatan kehadiran: 1. Absensi Manual / Kertas: Rawan manipulasi, rawan hilang, dan memakan waktu rekapitulasi yang tinggi. 2. Mesin Biometrik (Fingerprint) Konvensional: Sering gagal mengenali sidik jari yang kotor, berminyak, atau basah; menimbulkan antrean panjang di jam sibuk kerja/sekolah. 3. Sistem Cloud Murni (Pure Cloud-Dependent): Jika koneksi internet ISP luar mati (down) atau latensi tinggi, seluruh proses absensi di kantor menjadi lumpuh dan karyawan tidak bisa tap kartu. 4. Konfigurasi…

Rfid: common questions

What microcontroller does the Rfid use?

The Rfid is built around the ESP32-S3-DevKitC, from the ESP32 family.

How big is the Rfid PCB?

The Rfid measures 26.1 × 37.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rfid?

8 components, from 6 distinct parts. The full bill of materials is listed on this page.

Where can I download the Rfid design files?

From the LeafCodes/esp32s3-rfid-attendance repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rfid design in my own project?

The repository has no license, so all rights stay with LeafCodes. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Rfid without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
